There's just one issue. You'd have to develop it on your own coz you can't copy it nor will you have access to those blue prints like that of the bomb the Russians gave you along with the materials & tools required to build them like you'd later do to Pakistan
A good example of it is the J-7 where the Russians gave you incomplete shop drawings & documentation & it took you more than 2 decades to get it right. In the bargain you certainly learnt a lot , enginnering the best version of the MiG -21 which in large part was also due to western consultancy & avionics.
Our first N bomb was of an extremely low yield as was to be expected. We didn't have any support & learnt everything on our own thru trial & error.
If you think just because you've reverse engineered an ASML DUV lithography machine , you've arrived , congratulations. Come back here when you successfully churn out millions of 8 nm SMC nodes with yields matching your international competitors like TSMC , Samsung etc.
Besides those supply chains are also embargoed as far as you're concerned which means you develop everything in house.
1. Lithography machine is not a LCD TV, you sell it and then people enjoy Netflix on it. From the day one, the FABs are deeply joined the R&D. SMIC, Huawei, XMC ... ... were deeply involved, so the whole supply chains in China already integarted, which the sanction from USA actually stimulated the trend.
BTW, even the EUV idea is contributioned by Dr Lim from TSMC, the user of ASML.
2. Asking any IC students and small firms in China, they sent millions of thanks to US government. The IC students were worst pay jobs comparing guys working in TikTok and other gaming companies. Now they said they don't worry high salaries for next 20 yrs.
3. Except sanctions on pages, most forgein companies and people (especially from TSMC) are infact still selling things to Chinese IC industry insanely.
ASML sees another sharp rise in sales figures China

ASML’s share in the European tech market is on the rise, as China’s demand for DUV machines fuels the company’s revenue growth, even amidst challenges and export restrictions.

Chinese GDP is 100% as USA in 2014, and manufacture GDP is twice than USA+EU; so if they would built a whole supply chain on IC making. I see no barriers to build our own. At least it hires a lot!
